What potential pitfalls should be considered when passing HTML code in a PHP script, such as the issue of incomplete code being displayed?

When passing HTML code in a PHP script, one potential pitfall to consider is the issue of incomplete code being displayed if there are syntax errors or missing closing tags. To solve this issue, you can use the PHP `htmlspecialchars()` function to encode special characters in the HTML code before outputting it to the browser. This will ensure that the HTML code is displayed as intended without causing any syntax errors. 

<?php
$html_code = "<h1>Hello, World!</h1>";
echo htmlspecialchars($html_code);
?>
